Attornqy Fatented Nov. 12, 1929 UNITED STATES PATENT OFFICE LAWRENCE G. SCHWANZEL AND OLIVER A. KNISELY, OF TOLEDO, OHIO; SAID SCHWANZEL ASSIGNOR TO SAID KNISELY CURATIVE-BAY GENERATOR Application filed April 3,

This invention relates to new and useful improvements in ray generating machines particularly designed for therapeutic purposes and aims to provide a highly novel,

simple and extremely useful ray generating machine constructed to facilitate the ready projection of the rays onto various parts of the body for curing ailments of the body.

Generally the invention includes a domeshaped reflector into which projects the ends of a pair of carbon sticks through which an electric current is passed so that an arc will be formed between the ends of the carbon sticks or electrodes resulting in the production of a ray which is projected to the particular part of the body by said reflector.

An important object of the invention resides in the provision of means whereby the reflector may be raised or lowered or disposed at the proper point so that the rays will be projected in the proper direction.

A further and important object resides in the provision of means whereby the carbon sticks or electrodes may be simultaneously moved inwardly with respect to the reflector so that the proper spaced relation of the inner ends thereof may be maintained as said ends become burnt off.

A further and important object resides in so the provision of a device of this character which is designed with the purpose in mind of producing for therapeutic uses an instrument which will be practical, simple in construction, easy to operate and moderate in price.

VVith the foregoing and other objects in view as the nature of the invention will be better understood, the same comprises the novel form, combination and arrangement of parts hereinafter more fully described shown in the accompanying drawings and claimed.

In the drawings wherein like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a side elevation of my improved ray generating device, the reflector being disclosed partially in cross section,

Figure 2 is a top plan view of the device the reflector being fragmentarily disclosed in cross section,

1928. Serial No. 266,970.

Figure 3 is a sect-ion through the upper end of the device taken directly beneath the carbon stick holders,

Figure 4 is a detail horizontal section taken substantially upon the line kt of Figure 2 and looking in the direction of the arrows for more clearly disclosing the means whereby the carbon sticks may be simultaneously adjusted and maintained in a predetermined adjusted position,

Figure 5 is an enlarged fragmentary sec tion through one of the carbon stick holder clamps,

Figure 6 is a detail longitudinal section of one of the carbon stick holders.

Now having particular reference to the drawings, our novel device consists of a suit able weighted base 5 preferably mounted upon rollers or casters and from the center of which a hollow standard 6 within which is telescopically arranged a standard 7 the upper end of the hollow standard being constructed with a clamp 8 whereby the standard 7 will be rigidly secured to the standard 6 at any predetermined point therein this structure obviously permitting the length of the post formed by the units 6 and 7 to be regulated at'will.

Detachably arranged upon the upper end of the member 7 is a yoke 9 between the upper ends of the legs of which is adjustably pivotally supported a horizontal plate 10 the rear end of which is rounded and provided with a cross slot so as to provide a manipulating handle 11 for said plate. The inner end of this plate is formed or constructed with a suitably shaped bracket 12 to which is rigidly secured the inner closed end of a horizontally extending dome-shaped reflector 13 open at its outer end and provided within said open end with a screen 14.

The top surface of the plate 10 is formed adjacent its outer end on opposite edges with upstanding lugs 15-15 within openings in which are arranged the outer ends of hori zontal rods 16-16 that converge inwardly toward their opposite ends and are in turn arranged within sockets formed in the refiector supporting bracket 12, (see Figures 1 and 3). Loosely slidable upon these rods 16 are collars 1717 formed at their top sides with split clamping sleeves 18-18.

At their under sides these collars 1717 are formed with depending pins 1919, (see Figure 4) that have sliding engagement within longitudinal slots 2020 at the opposite ends of a cross strap 21 equipped intermediate its ends and in its bottom side with a block 22 slidable within a longitudinal slot 23 in the plate 10. This block is formed at its bottom side with a threaded socket for receiving a threaded pin 23 upon the inner end of a clamping head 24;, which when screwed inwardly will frictionally engage the under side of the plate 10 to prevent movement of the pin connecting strap 21 of the plate 10.

The invention further consists of a pair of carbon sticks or electro holders 25-25. Each holder consists of a pair of concentrically arranged metallic tubes 26 and 27 the inner'end of the inner tube being split as disclosed in Figure 6. The opposite end of the innermost tube is provided with an internally threaded sleeve 28 within which the adjacent end of the outermost tube 27 is threaded. By turning this sleeve in one direction the outermost tube 27 will be drawn rearwardly so that when the split end of the innermost tube is uncovered it will eXpand to permit a generally conventional carbon stick 29 to be arranged therein.

An opposite turning of the sleeve 28 will clamp the carbon stick firmly within the holder.

The outermost sleeve 27 of each carbon holder is formed with a circumferential groove 30 around which a conducting wire 31 is to be arranged, a fiber sleeve 32 being arranged over the inner end of each holder and within the respective split sleeve 18 of the said sliding collars 17. From these fiber sleeves 32 the conducting wires 31 lead to a conventional rheostat 33 arranged upon the standard of the device as disclosed in Figure 1.

The rear end of the reflector 13. directly above the bracket 12 is formed with a pair of spaced openings 34.34 through which the ends of the carbon stick 29 project. Obviously as the points of the sticks become worn they may be fed into the reflector by loosening the member 24 and sliding the strap 21 inwardly upon the plate 10. By reason of the converging rods 16, 16, the inner ends of the carbon sticks always project toward each other so that the proper spaced relation of the ends of the sticks may be readily attained.

In view of the foregoing description when considered in conjunction with the accompanying drawings it will be apparent that we have provided a highly novel, simple and highly eiiicient curative ray generating device that is well adapted for all of the purposes heretofore designated and even though we have herein shown and described the invention as consisting of certain detail structural elements it is nevertheless to be understood that some changes may be made therein without affecting the spirit and scope of the appended claim.

Having thus described our invention what we claim is In a ray generating apparatus comprising a base, a reflector mounted on said base, and formed with a pair of closely spaced openings, said base being provided with a slot extending parallel with respect to the axis of the reflector, a block slidable within the slot, a cross member having slots in each end portion upon the block, u standing constructions on said base, a pair 0 spaced and convergedly mounted guide rods mounted on said con structions, a collar slidable on each rod, a clamp structure on each collar, a carbon stick holder disposed through each clamp structure, and complementary means between the collars and the cross member whereby the co]- lars may be slid inwardly on the cross member as the collars are simultaneously moved toward the reflector for feeding the carbon sticks carried by the holders through the openings in the reflector, said complementary means consisting in a pin depending from each collar and disposed through one of the slots in the cross member.

In testimony whereof we aflix our signatures.
